Hey student,

A Doctor of Philosophy is the most common degree at the highest academic level awarded following a course of study. PhDs are awarded for programs across the whole breadth of academic fields.

YES, definitely you can do Phd after completing your master's in Life Science from Distance learning. Only the condition is the degree of your masters must be from recognised university by NACC and UGC.

All the best student,

Hope this helps you.
